Abstract

The invention provides a technique and a product in which a frequency converter (1) supplying electric power to, for example, a motor, a downsizing, lightening or the like is realized while providing a filter apparatus reducing electromagnetic noises and the like. The filter apparatus reducing electromagnetic noises and the like is provided near a main circuit terminal board of the frequency converter (1), and the filter apparatus is connected directly to a main circuit terminal as a wiring drawing portion (R,S,T) of the frequency converter (1). Part of a housing of the frequency converter (1) and part of a filter housing (2) are fitted to each other to fix the filter housing (2) to the frequency converter (1).
